A certain medication is available only in 400 μg tablets. If the patient needs to take 2.4 mg per day, how many tablets must she take? Help me please. SIMPLIFY YOUR ANSWER. Expert only.
Answer: 6 tablets.
Step-by-step explanation:-Given:
• A certain medication is available only in 400 μg tablets.
So, in milligrams :- 0.4 mg
• It is also given that the patient needs to take 2.4 mg per day.
Solution:
So, in order to know how many tablets she should take, please do as following:-
[tex] \frac{2.4}{0.4} [/tex]
[tex] = > \: 6[/tex]
Hence, she must take 6 tablets per day.

Suppose that Paul's checking account shows a balance of $725.35 at the beginning of the month. During this month,
he makes deposits of $472.25, $175.35, $194.50, and $317.85, and he writes checks for $150.30, $237.60,
$45.75, and $257.85. Find the end-of-the-month balance in his account.
Answer:
$ 1,193.80
Step-by-step explanation:
Balance + deposits =
725.35+472.25+175.35+194.50+317.85 = $ 1,885.30
$1,885.30 - withdrawals =
1885.30 - 150.30-237.60-45.75-257.85 = $ 1,193.80

Recibes un cierto embarque con la promesa de que no tiene más del 15% de ítems defectuosos. Si la proporción o porcentaje de ítems defectuosos es mayor queel15%,puedes solicitar una devolución. Tomas una muestra aleatoria de 10 ítems y encuentras 6ítems defectuosos. Ciertamente 6es más del 15% de la muestra.Presentas tu queja y te responden: el embarque tiene menos del 15% de ítems defectuosos. Si usted encontró 6 en su muestra, fue simplemente coincidencia o mala suerte, porque el embarque sí cumple con lo establecido.¿Cuál es la probabilidad de que realmente haya sido fruto de la coincidencia? ¿Cómo argumentarías para conseguir que te devuelvan el dinero?
Usando la distribución binomial, se encuentra que hay una probabilidad de 0.0012 = 0.12% que realmente haya sido fruto de la coincidencia. El argumento para conseguir que te devuelvan el dinero seria de que 6 ítems defectuosos es un resultado inusualmente alto.
Para cada ítem, solo hay dos resultados posibles. O está defectuoso o no lo es. La probabilidad de que un ítem sea defectuoso es independiente de cualquier otro ítem, lo que significa que se utiliza la distribución binomial para resolver esta cuestión.
Distribuición binomial:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Los parámetros son:
n es el número de ensayos.p es la probabilidad de éxito en un ensayo x es el número de éxitosLa media de la distribución binomial es:
[tex]E(X) = np[/tex]
La desviación estándar de la distribución binomial es:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Una medida se considera inusualmente alta si está más de 2.5 desviaciones estándar por encima de la media.
En este problema:
10 ítems, o sea, [tex]n = 10[/tex]15% defectuosos, o sea, [tex]p = 0.15[/tex].La probabilidad de que realmente haya sido fruto de la coincidencia es P(X = 6), o sea:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 6) = C_{10,6}.(0.15)^{6}.(0.85)^{4} = 0.0012[/tex]
Probabilidad de 0.0012 = 0.12% que realmente haya sido fruto de la coincidencia.
Para el argumento:
[tex]E(X) = np = 10(0.15) = 1.5[/tex]
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{10(0.15)(0.85)} = 1.13[/tex]
[tex]6 > 1.5 + 2(1.13)[/tex], o sea, el argumento para conseguir que te devuelvan el dinero seria de que 6 ítems defectuosos es un resultado inusualmente alto.

Show that the equation x^4/2021 − 2021x^2 − x − 3 = 0 has at least two real roots.
The roots of an equation are simply the x-intercepts of the equation.
See below for the proof that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] has at least two real roots
The equation is given as: [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]
There are several ways to show that an equation has real roots, one of these ways is by using graphs.
See attachment for the graph of [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]
Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)
From the attached graph, we can see that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] crosses the x-axis at approximately -2000 and 2000 between the domain -2500 and 2500

What can you divide a2b5 by to get a quotient of 1?
9514 1404 393
Answer:
a^2b^5
Step-by-step explanation:
Anything divided by itself is 1.
That is, anything multiplied by its reciprocal is 1. This value (the reciprocal of the expression) is called the "multiplicative inverse." Its value is that the product of an expression and its multiplicative inverse is 1, the multiplicative identity element. (Anything times 1 is itself.)
So, to get 1 as a product, multiply by 1/(a^2b^5), which is to say, divide by a^2b^5 to get 1 as a quotient.
What is 3/7÷2/7
Also 3/4÷5/6
Answer:
3/7 ÷ 2/7 = 3/2
3/4÷5/6 = 9/10
Step-by-step explanation:
The key rule to understanding how to divide fractions is...
KEEP SWITCH FLIP!!!
Basically, you keep the first fraction, switch the sign from division to multiplication, and flip the other fraction...
Here's how you would go about this:
3/7÷2/7
Keep 3/7 and switch ÷ to multiplication
3/7 · 2/7
Now flip 2/7 so it becomes 7/2
3/7 · 7/2
Now multiply across!
3 · 7 = 21
7 · 2 = 14
You get 21/14...but don't forget to simplify!! Divide 21 and 14 by 7 to get 3/2!
And now...for 3/4 ÷ 5/6, you do the exact same thing!
Keep...3/4
Switch... ÷
Flip...5/6
And you should get:
3/4 · 6/5
Multiply across...
= 18/20
Simplify!
= 9/10
I hope this helps clarify any confusion you may have had!

We know that the vertex(lowest point) of [tex]|x-h|[/tex] is [tex](h, 0)[/tex].
By inspection, we can see that the vertex of the graph is [tex](4, 0)[/tex].
So, the lowest point of [tex]F(x)=|x-h|[/tex] is [tex](4, 0)[/tex], which means [tex]\boxed{h=4}[/tex]

0=|x-h|
x=h,

The area of a square region is 529 mi2. What is the perimeter of the region?
Answer:
92 miles
Step-by-step explanation:
The area of a square is Length x Width. All sides of a square are equal in length so length = width. This is the same as saying x = length and x = width so X times X equals the area. X times X is X².
This tells you that X² = 529 mi². X would equal the square root of 529 which is 23. 23 x 23 = 529.
Each side of the square is 23 miles. The perimeter is equal to side 1 plus side 2 plus side 3 plus side 4. Again since it is a square all sides are equal.
This mean you can just take 4 x 23 miles. The perimeter = 92 miles
Answer:
The perimeter of the region is 92 miles
Step-by-step explanation:
For a given Square
Area = 529 mi²
Now, To find area we use formula
A = (l)²
529 = l²
√529 = l
23 = l
l = 23 miles
Now, To find perimeter of square we use,
P = 4l
P = 4 (23)
P = 92 miles
Thus, The perimeter of the region is 92 miles
